The following are the specifications for all the YES WorldWatch V7 watches:
Across the planet there are upwards of 20 different Daylight Saving Time systems. The WorldWatch incorporates all of them in the programming for the relevant cities and automatically adjusts for them. If need be, DST can also be turned ON and OFF manually.
The V7 is a 24-hour clock overlaid with the daily, monthly and seasonal cycles of the sun and the moon. At a glance you can tell time for sunrise, sunset, zenith, twilight and much more.
